No. Since the secondary thread does not own the UI or the message pump, it has no choice but to post a message to the main thread indicating that something needs to be updated.

Unless you don't know until runtime how many labels you'll need, you can create them as not visible. Then at runtime, you can alter their text and position and show them as needed. You can also add controls at runtime, of course, but more often than not it's not actually needed. -- jlr http://jlamas.blogspot.com/[^] UNICODE in edit control John R. Shaw5-Jul-05 17:23 John R. Shaw 5-Jul-05 17:23  I've been trying to get the edit control in my dialogbox to accept UNICODE characters (WinXP): 1) Compiled application for UNICODE, the richedit control accepts UNICODE but the standard edit control does not. 2) Tried setting font of control to use a TT unicode font (WM_INITDIALOG); that didn't work. 3) Tried editing the .rc directly to use UNICODE font; that didn't work. 4) Searched MSDN for solution; that didn't work, but maybe one of the samples applications show how to do it. 5) Currently searching CP, then it is off to the rest of the www. Note: I know the edit control will accept MBCS, since it has been able to do that since Win3.1. Q. Does anyone know why the above solutions don't work?

Troelsen Re: UNICODE in edit control Jose Lamas Rios6-Jul-05 3:26 Jose Lamas Rios 6-Jul-05 3:26  Are you using VS2003 or VS6? I first tried with VS2003. In the project settings (Configuration Properties / General) I changed "Character Set" to "Use Unicode character set". This takes care of removing _MBCS and defining both UNICODE and _UNICODE. Rebuilt and everything worked fine. Then tried with VS6. In project settings (C/C++ tab, Category General, Preprocessor definitions) removed _MBCS, and added UNICODE, _UNICODE. In the Link tab, Category Output, I set Entry-point symbol as wWinMainCRTStartup. Rebuilt and everything worked fine too. In both cases I started with an AppWizard-generated dialog-based application and just added an edit control to the dialog template. Try getting the text from the edit and inspect its content so as to determine if you are having problems with the text itself or if it's just a problem in how the edit displays it. I also suggest testing by creating a project from scratch as I did. -- jlr http://jlamas.blogspot.com/[^] Re: UNICODE in edit control John R. Shaw7-Jul-05 14:56 John R. Shaw 7-Jul-05 14:56  :-DVery good! I should have checked in yesterday. What I did was to check the size returned by sizeof(TCHAR) and found that it was still 1. So I checked the settings and found that _MBCS was defined before UNICODE,_UNICODE. So I removed it from my UNICODE builds. Naturaly, this caused some other problems, which I am working on now. P.S.

Re: what is that high-character? Jose Lamas Rios5-Jul-05 17:48 Jose Lamas Rios 5-Jul-05 17:48  I suggest you start by reading The Absolute Minimum Every Software Developer Absolutely, Positively Must Know About Unicode and Character Sets (No Excuses!)

But I do find it funny and enlightening at the same time JWood wrote: there is also http://www.flipcode.com/articles/article_advstrings01.shtml[^] I didn't know that; it's a good one too. I think both articles complement each other well. Joel's is more conceptual. It does a very good job at explaining the character sets evolution, and the concepts behind each of the names in the dance: what's ASCII, what's ANSI, what's a code page, etc., and Unicode, of course. In particular, it explains the distinction in Unicode between the character set, that is, the mapping between characters and numeric values (and no, it isn't limited to 65536 characters), and the possible encodings to use when you need to represent Unicode code points in memory or disk (and no, it isn't always stored as 16 bit per char). The article you linked, on the other hand, is more implementation oriented, and as such it covers details that aren't present in the one from Joel. Although is somewhat conceptually wrong when it talks about Unicode and Unicode-encoded-as-utf-16 as if they were exactly one and the same, that doesn't actually hurts much, because of its focus on Visual C++ and Win32, where that equivalence is almost always true, and even MS documentation treat them as the same thing. So, to any beginner, I'd recommend starting with Joel's article so as to better understand the concepts, and then reading this other article by Fredrick Andersson to see how these concepts are implemented and used with Visual C++ and Win32 APIs. -- jlr http://jlamas.blogspot.com/[^] Re: what is that high-character? JWood6-Jul-05 12:18 JWood 6-Jul-05 12:18  Yeah certainly Joel has all the interesting theoretical points. I'm a practical type programmer so the Andersson article appeals a little more to me. This is an issue that kind of struck me when I realized it - "Whoh, when did this happen and why wasn't I told?" I am actually working on a piece of code to update to MBCS / Unicode all the functions in fairly large program so that it is ready for the European / Asian market. Mobile source control options? charlieg5-Jul-05 15:14 charlieg 5-Jul-05 15:14  I'm a source code control ART (anal retentive type). It's saved my butt on a number of occasions. However, over the past 18 months, my work is more mobile. Most of the code resides on my laptop, and 2-3 days each week I am in "the lab" - with access to servers, etc. As a result, application of VSS is not really practical. So, I'm looking for some kind of source control tool that will allow me to have a database on my laptop but also allow me to synchronize with the "main" repository when I have the connection. Any ideas? C. Gilley Will program for food... Whoever said children were cheaper by the dozen... lied. Re: Mobile source control options?
